MAX5813/MAX5814/MAX5815

Ultra-Small, Quad-Channel, 8-/10-/12-Bit Buffered

Output DACs with Internal Reference and I C Interface

General Description

Benefits and Features

The MAX5813/MAX5814/MAX5815 4-channel, low-power,

8-/10-/12-bit, voltage-output digital-to-analog converters

(DACs) include output buffers and an internal reference

that is selectable to be 2.048V, 2.500V, or 4.096V. The

MAX5813/MAX5814/MAX5815 accept a wide supply

voltage range of 2.7V to 5.5V with extremely low power

(3mW) consumption to accommodate most low-voltage

applications. A precision external reference input allows

rail-to-rail operation and presents a 100kI (typ) load to

an external reference.

The MAX5813/MAX5814/MAX5815 have an I²C-compatible,

2-wire interface that operates at clock rates up to

400kHz. The DAC output is buffered and has a low sup-

ply current of less than 250FA per channel and a low

offset error of Q0.5mV (typ). On power-up, the MAX5813/

MAX5814/MAX5815 reset the DAC outputs to zero, pro-

viding additional safety for applications that drive valves

or other transducers which need to be off on power-up.

The internal reference is initially powered down to allow

use of an external reference. The MAX5813/MAX5814/

MAX5815 allow simultaneous output updates using soft-

ware LOAD commands or the hardware load DAC logic

input (LDAC).

ꢂmꢆedances

A clear logic input (CLR) allows the contents of the CODE

and the DAC registers to be cleared asynchronously and

sets the DAC outputs to zero. The MAX5813/MAX5814/

MAX5815 are available in a 14-pin TSSOP and an ultra-

small, 12-bump WLP package and are specified over the

-40NC to +125NC temperature range.
